Love this site!
Before I tell the story, I just want to tell you about my backyard. It is completely private (surrounded by huge evergreen trees on all sides) except for windows from the house facing it, so I felt very secure and alone.
I had just had a swim in my pool and I was air drying on the lawn chairs (wearing my swimsuit because my dad was out there). When he left I started feeling very horny from being in a sexy spandex bikini and the possibility of being watched made me even more horny. I made sure nobody was watching and I squeezed my nipples. It felt SO GOOD, and I felt my pussy getting very wet. I looked around again and I slipped my hand under my bikini bottoms and massaged my slit and I got even more slippery.
I slowly inserted a finger and rubbed my clit slow in circles, then pulled out my finger and massaged my slit. Then I rubbed my clit very fast, and shortly after I got a very intense and wonderful orgasm. But then my heart skipped a beat when I noticed that my parents bedroom window was open and I pulled my fingers out of my pussy quickly and cum poured out. They never said a word about it to me so maybe they never noticed, but it made for a very wonderful orgasm when I considered the fact that I might have got caught.
